For the third quarter of 2017, the Company reported net sales of $438.6 million, which was an increase of 2% compared to net sales of $429.6 million in the third quarter of 2016. The 2% quarter over quarter growth in net sales was driven by an increase of 12% in international auto-dimming mirror unit shipments. The underlying light vehicle production in Europe, Japan, and Korea was up 7% overall in these markets which comprise the majority of the Company's international shipments. The growth in international auto-dimming mirror unit shipments was partially offset by a quarter over quarter decrease of 7% in North American auto-dimming mirror unit shipments which in large part resulted from an 8% quarter over quarter decline in North American light vehicle production. During the third quarter of 2017, North American light vehicle production schedules decreased by approximately 3% as compared to the Company's original estimates for production, primarily due to intermittent plant shutdowns, which negatively impacted the Company's net sales growth on a quarter over quarter basis by approximately the same percentage.

When compared with the third quarter of 2016, the gross margin declined from 40.5% to 39.0% in the third quarter of 2017, primarily as a result of annual customer price reductions that were not fully offset by purchasing cost reductions, as well as the Company's inability to leverage fixed overhead costs due to the lower growth in sales on a quarter over quarter basis. However, the gross profit margin improved sequentially from 37.7% in second quarter of 2017 to 39.0% in the third quarter of 2017, primarily as a result of improvements in product mix and manufacturing efficiencies.

Income from operations for the third quarter of 2017 decreased 4% to $129.1 million when compared to income from operations of $134.2 million for the third quarter of 2016, due to the lower quarter over quarter gross profit margin percentage, which more than offset the quarter over quarter increase in net sales.

Other income increased to $1.8 million in the third quarter of 2017 compared to $0.1 million in the third quarter of 2016, due to an increase in investment income during the most recently completed quarter as compared to the same quarter last year.

Net income for the third quarter of 2017 decreased 2% to $90.2 million compared with net income of $92.1 million in the third quarter of 2016.

Earnings per diluted share in the third quarter of 2017 decreased 3% to $0.31, compared with earnings per diluted share of $0.32 in the third quarter of 2016, as a result of the decrease in net income.

Automotive net sales in the third quarter of 2017 were $428.2 million, an increase of 2% compared with automotive net sales of $419.8 million in the third quarter of 2016, driven by a 5% increase in auto-dimming mirror unit shipments on a quarter over quarter basis.

Other net sales in the third quarter of 2017, which includes dimmable aircraft windows and fire protection products, were $10.5 million, an increase of 6%, compared to other net sales of $9.8 million in the third quarter of 2016.

Share RepurchasesDuring the third quarter of 2017, the Company repurchased 3.2 million shares of its common stock at an average price of $17.51 per share. As of September 30, 2017, the Company has approximately 14.9 million shares remaining available for repurchase pursuant to its previously announced share repurchase plan. The Company intends to continue to repurchase additional shares of its common stock in the future depending on macroeconomic issues, market trends and other factors that the Company deems appropriate.

Debt RepaymentDuring the third quarter of 2017, the Company paid down $8.1 million of debt on the Company's term loan, which in combination with its normally scheduled principal repayment of $1.9 million resulted in a total repayment of $10.0 million during the quarter. The Company expects to continue, at its discretion based on previously disclosed factors, to pay additional principal toward its debt in the future, in anticipation of such debt maturing on September 27, 2018.

Future EstimatesThe Company’s forecasts for light vehicle production for the fourth quarter and full year 2017 are based on the IHS Automotive October 2017 forecast for light vehicle production in North America, Europe, Japan and Korea.

Based on the October 2017 IHS light vehicle production forecast, current forecasted product mix and expense growth estimates, the Company has updated certain of its 2017 guidance. For the fourth quarter of 2017, the Company estimates that revenue will increase between 5% and 10% versus the same quarter last year.
